TRAIN sI'G-NAEING DEVICE.

A To all /wwm it may concern.'

Be it known that I, ELMER M. JoNEs, a citizen of the United States, residing at Atlanta, in the county of Fulton andState of Georgia, have invented a certain "new and useful Improvementgin Train Signaling Devices, of which the following is a. full, clear,

and `exact description, reference being had to -the accompanying drawings.

This invention relates to a railway track device designed to cooperate with a locomotive, or other 'moving vehicle, and to control mechanism thereon either for giving a signal, applying t-he brake or causing other indication. Accordingly, I `have called the mechanism la train signaling device, though it is to -be understood that the particular character of the signal-whether a signal proper or the direct operation of controlling mechanism-is immaterial. Such dcvioehas a movable abutment adapted to be engaged by the vehicle as it -moves past the saine.

The object of the present invention is to provide reliable and effective mechanism for withdrawing the abutment and maintaining it o'ut of the path of the vehicle-during safety 'the face of the shoe and periods, and for vreturning it into such path durin a danger period. It is also important tat the abutment should be automatically returned to active position in ease 0f a defect in the track signaling-equipment. The present invention provides such retractingr and automatic'returning mechanism, which form is both simple and efficient.

The invention consists of the means employed to efect these results, as hereinafter more fully explained, and as summarized in the claims.

In the drawings, lFigfgu-re 1 is a vertical section through the casing containing my track device and showing the parts in normal position. This section is mostly on a plane directly behind the front door of the casino, but the pivot `of the shoe which is raise by the trip lever is also shown,though it is on a plane in front o the plane yof 'the rest of the figure; Fig. 2 is a Sectional plan; Fig. 3 is a vertical section corresponding to Fig. 1, butshowing the parts in danger posif tion; F 1g. 4 is a vertical section al; right angles to Figs. 1 and 2, taken partly along partly in front thereof.

As shown in the drawings, 1G represents a suitable or ramp pivoted at ll to the Specification of Let'ters Patent.

xportion 12 of lthe casing. This shoe'ha's a ieg 1-3'dep'endi1ng into the-easing and having -a pin-and-slot connection with a. -pair of arms M which straddlethe leg. These `arms a're loosel mounted on a shaft 15. Between them an rigid on` e shaft is :in arm '16 carrying a vpin i7 adapted to abut nganst the underside-of ithearms 14.-. Rigid on this sha-Et Ialso is a head 20. Now, when this' head is rocked, i'ts *upper portion 'toward `the right in Fig. 4, 'the ramp 10 is raised; while, when `the head is rocked in the opposite direction, no effect is had `on the ramp, because "the pin l17 simply `moves idly away ffrom engagement with the-arms 14.

In my prior application N0. 587,053, tiled October, 1910, a vctmstruction such -as above describedv is shown and claimed. In that construction, the member corresponding to the present -head 2O -is' extended upwardly and forms wn abutment 'lever adapted-"to be engaged 'by the locomotive and swung to raise the ramp. In the present construction', the head 20 sl'idably cai'ries -a bar which has a doveta-iled or 'tongue and groove connectibn with the head, as shown. This head with its bar, constitute 'a lever corresponding to the abutment lever of Ithe application reerred to, Afor `v'vhen the Abar 23 is elevated,

it may be engaged by a locomotive and th@ .85

however, provides means for lthawing the bar 23 downwardly lalong the head '-20 to retract it to idle position. This mechanism will now -be described.

Mounted 'on the face of the bar 23 within the portion 22 of the casing, is -a stud 25 which, in danger position, is coaxial 'with the shat 15. Around this stud 25 is a 'loose yoke 27 which is pivotally mounted between the two lower arms 'of a forked bar 30. This bar is also forked at its upper end and there straddle's and is ivoted to a block 31 which has 4a limited swivel 4conr'lec'tion with a lever 35. This' lever is pivoted at 36 between 'a pair-fof standards 37 and on the `opposite Side 'of these standards there is a weighted end 38. This Weighted 'end is prefer-ably made l(uite heavy, so that its tendency to fall elevates the other end of the leverand; would maintain the abutment bar clef vii-ted in the position shown in Fig. 3, it thizr heavy -efnd were not held up, 'as it may 'he by latches, as shown in Fig. 1. Such latches lit? and the mechanism for'raisin the weighted end of the lever -will now be cscribed.`

As shown in Fig. 2, the le r 35 is intermediately slotted and munted on the axle 36. This wheel is shown `fs"living on its periphery a sprocket chain 41 which gears with a pinion 42 onthe armature shaft of a motor 43. Mounted within the heavy end of the lever, is a pinion 44, meshing also-with the sprocket chain. This ,pinion is rigid on its shaft, and also rigid on this shaft isa notched wheel 45 with which cooperates a latch 46 which constitutes or carries the armature ofimagnet 50. Now, if the magnet 50 -is energized, thej latch 46 holds the wheel 45 againstrptation'; thereby the pinion 44 is locked to the lsprocket; chain 41 and the .rotationof the motor armature in the proper direction will accord' ly'elevate the heavy end of the lever illi draw down the abutment bar 23v into the position shown in Fi '1.

When theever is carried by the 'motor in the position shown vin 1, a dog en the lever under the intluencecf a spring 56- may snapacross and above the end of a lever 57 which is connected by a link 58 with a bell crank' 59 which constitutes or carries the armature for a magnet 60. When this magnet is energized, it holds the latch lever 57 in the positio shown in Fig.- 1 and may thereby sustain e1-weighted end of the lever 35. A dener ation ofthe ets 50 and (i0 releasesft weighted end `cti-the lever and allows thepartsI to returngto the danger position, shownf-in .Fig. 3..

e above described 1 motor and latch. 'mechanism is shown inconnectioiwitl a semaphore in my priorl apPiati9nf;N0 561,967, filed May 13th, ialogzand "iclaimed thereinl broadly, so that refernce sholdjbe" made to thata plication forI covering thisportiono the mechanisnn' Fig. 1shows circuits which latches shown. In this view A re rlents a relay connected with any suita le'. track signal system. yBris an. armature offi this relay which opens or closes the local circuit.`

Thiscircuit divides into two' main branches which may be traced asfollows: Starting from' the battery C, one of the branch circuits passes via the line D andfthepline E throu' h the magnet 60, thence via the lines F an G to the armature B and thence to the battery. One part of the otlieli` branch starts from the battery C and passes via the line H to thev motor and from .thence via 'the line J to a terminal 63 of a suitable switch. From the otherterminal 64 of this switch, the line K'leads to the line G and" thence through the'armature B to the bat-- tery. The other part of'this socalled sec ond branch passesl via the linie D through In this glottgdportion is a wheel`40.'

may carry :the current for controlling thevr magnetsv and T e final the magnet 50 to the line L, thence to the line J, to the switch, and returns the same .as the motor line. The switch member 64 is shown as carried by a bell crank which is connected bya link 65 withvthe lever-35 on its weighted side.

The result of the circuits shown is that when the magnet A is energized, the local circuit throu h the magnet 60 is closed; and

the circuits t rough the motor and through the magnet 50 are closed if the parts are in `the-position shown in Fig. 3,-that is, if'

the weighted end ofthe oerating lever is down and V'the 1abutment ar is elevated. Accordingly such' closure causes,l the motor to rotate and elevate the weighted end of the lever until its'dog 55'passes above'the latch i 57, thereby holding the lever inthe position `shown in Fig. 1.r As the lever is coming into thisl'tn'al position, the link 65 moves the switch 64 to open the circuit to the motor and magnet 50. As long as-the magnet A remains energized, the parts remain in. the gosition shown in Fig. 1 with the abutment ar retracted to. idleposition. When themagnet. A becomes denergized, either from the operation of` the track signalsystem or the breaking of the circuit, which may result froml the trackV bein -occupied or a broken rail, or a defectf in c-signal system, or otherwise,whatever the cause may the denergizationof the ma etlAdrop's the armature B, breaks. the ocalfcircuits,

allows the wei tede'ndyof the lever to dro elevating the' a kutment bar so that it-stan 's' in the a'thv of'an advancing vehicle, and 1s ada te to be engaged thereby and givean indication on the vehicle. A

Inv order that thev abutment bar -23 when retracted'may beheld stationary in a vertical position, l[ provide the" following mechanismz--Mounted on the-stud 23 are :a Apair oflinks 70 whihzlareconnecdat -their lower endsf-w-ith-a pair of belll cranks 71, respectively'pivoted at 72xand 73 to ears carried by 'the casing.-

other arms of' these bell cranks carry 7 4 which stand opposite the sides of the' head Near the lower end of this head, these -sidesare outf wardly, as shbwnatl Now, tht.l result of this construction .that when the piiil25 is loweredv to retract the bar 23, the same movement automatically 'swings 1nwardly the rollers 74, one-.of which will engage -the side of head' 2G, if the same'gbe ti pcd, and bring it into-vertical osition. osition of theroller 74 is shown in dotted ines in Fig. 4, this final position holdin the head ybetweenzgwtwo rollers. Exten ing upwardly from ii'nt'tomf the casing is a recessed lug 78 which 1s adapted to receive the lowerend of the bar 23 when it is retracted. The recess has a Haring mouth caused by the bevels 79.V As the lever is being drawn downwardly, a corner-of its lower .end may engage one of these bevels 79, vbut the continued downward movement straightens the bar so that in its lowermost position it is necessarily vertical and is rigidly embraced bythe jaws 78, which thereby lock it against displacement. This prevents the lever being ltampered with.

The Vring 27 surrounds ithe :pin 25 with considerable looseness, so that the action of the mechanism :takes place with a considerable blow when the .weightedend of the lever raises fthe abutment bar. This blow will break any temporary binding, such as frost or ice. By having the universal joint connection between ythe raising lever and the abutment bar, no. harm will result if the lever should l.be -struck before quite finishing the up stroke, such action `not causing any twist, but 'the universal .joint 'link adapting itself 'to -the new position. The abutment bar it is to be :understood is never high enough to be engaged by the locomotive device until the lower end-.of 'it has passed Vout o'f the 'locking fjaws.
